Problem 233 In Fig. P-231, a force P intersects the X axis at 4 ft to the right of O. If its moment about A is 170 ft·lb counterclockwise and its moment about B is 40 ft·lb clockwise, determine its y intercept.
Solution 233
Resolve force P into components at its y-intercept
Thus, y intercept of force P is (0, -8/3). answer
